First thing which came to my mind id twitter.So i checked ASIS twitter handle. Later i found that usually a guy named factoreal is the main guy in hosting asis-ctf.When you check his twitter photos there you go,you see the given hint "fact or real" and the motto in the picture : "NO+$=YES"
Flag is ASIS_md5(NO+$=YES)
FLAG : ASIS_d25b9c2f1c29e49e81e8fdfaf4d16fc6
